Summary: Stimuli-responsive core-shell microgels with zwitterionic hydrogel core and temperature-responsive poly[oligo(ethylene glycol)methacrylate-co-2-(2 '-methoxyethoxy)ethyl methacrylate] (P(OEGMA-co-MEO(2)MA)) shell were prepared by inverse miniemulsion RAFT polymerization. A water-soluble block copolymer emulsifier composed of a hydrophilic/lipophilic P(OEGMA-co-MEO(2)MA) block and a hydrophilic PMPC block was used to stabilize the emulsion. The resulting core-shell microgels exhibited stable dispersion in both chloroform and water, and showed temperature-responsive behavior.

Summary: This study proposes a core-shell nanorod surrounded by a Cu shell with a C core and investigates its absorption properties in solar absorption spectroscopy. The results show that this nanorod can reduce the cost while maintaining high solar absorption efficiency and significantly impacts solar energy absorption. Compared with single Cu NPs, the core-shell nanorods have a wider absorption band and higher resonance absorption peak.

Summary: In this report, Au@Ag core-shell nanorod structures were developed for contaminants sensing by SERS. The silver shell thickness and plasmon wavelength were tuned by changing coating time and silver precursor amount. These structures showed ultra-sensitive detection ability for Nile blue A dye and Fenobucarb pesticide sensing. The Au@Ag core-shell sample with minimal silver shell thickness exhibited the highest Raman enhancement factor due to optimal enhancement of the electromagnetic field of bimetallic structures. This report demonstrates the potential applicability of combining unique features of two plasmonic metals in SERS-based analysis.

Summary: The glass transition temperature (T-g) has a strong impact on the physicochemical properties of a polymer. Coating a material with polymer nanocapsules with different T-g values can provide the material with diverse properties. In this study, polymer nanocapsules were introduced onto glass substrates and the effect of polymer T-g on the surface properties of the coating was analyzed. It was found that the microstructural and microbehavioral properties of the coating surface depended on the T-g values of the synthesized core-shell polymer (CSP) particles.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.
